Usage
What does Aries mean? Aries is the name of a constellation that is interpreted as resembling a ram. It can also be referred to as the Ram. A constellation is a group of stars that appear near each other in the sky—especially a group that has been given a name. Aries is considered one of the 12 zodiacal constellations—constellations that appear within a particular portion of the sky called the zodiac. In astronomy, the zodiac is the band of sky along which the paths of the sun, the moon, and the planets appear to move. Despite its basis in astronomy, the word zodiac is mainly associated with and most often used in the context of astrology, the nonscientific practice in which the positions of heavenly bodies at certain times are thought to influence or be correlated with human behavior and events. In astrology, zodiac refers to a diagram (often a circular one) representing the zodiac belt and showing the symbols associated with each of the 12 constellations or sections, which are called the signs of the zodiac. Aries is one of these signs. It is situated between Pisces and Taurus and is considered the first sign of the zodiac. The other signs of the zodiac are Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, and Aquarius. The position of the sun in a particular portion of the zodiac at the moment of a person’s birth is thought to correlate with their personality. This is what people are referring to when they talk about their zodiac sign (or star sign or often just sign). People whose sign is Aries are those born between March 21 and April 19. The word Aries can be used as a noun to refer to someone who is born during this time, as in I was born in late March, so I’m an Aries. The word Arien can be used to mean the same thing. It can also be used as an adjective form of Aries. Aries should not be confused with Ares, the name of the Greek god of war. Example: My favorite constellation is Aries, and not just because I’m an Aries!
